5 GENERAL
DESCRIPTION
The A100C is a single phase meter for domestic applications of up to 100A.
The meter offers Class 1 or 2 accuracy, the option of IrDA or IEC 62056 - 21 (formerly
IEC 1107) communications and security data as standard.
The following versions of the A100C are available:
Import kWh – one or two rates
Import kWh – one or two rates, Power flow insensitive (See Section 9)
Import and export kWh – one or two rates
A high contrast, large character Liquid Crystal Display that uses chevrons to indicate the
active element can support any language by appropriate legends on the nameplate.
The meter stores comprehensive security data that can be included in the display
sequence.
The A100C has the option of IrDA or IEC 62056 -21 communications.
The IrDA variant is read only and reads the meter data electronically using a PC or
handheld device. As an option the meter auxiliary terminals can be configured at
manufacture to transmit the same absolute data as the IrDA port or to transmit a pulsed
output.
The IEC 62056 - 21 variant of the meter offers bi-directional communications allowing
reading of all stored data and the programming of ‘personality’ data. Access to the
various items is controlled by a multi-level password system. As a manufacturing option,
a pulsed output is available via the meters auxiliary terminals.
